Recently, in 14-June-2015 i have visitied the Amature Radio Club in Trabzon city / Turkey YM7KA and i have met also very nice people there and i did some SSB and CW QSO's from their station .
Now you can find me from time to time on remote base of my friend Dom 3Z9DX as SP9/YI1RZ , Physically i am in Turkey now in Gumushane city NE of Turkey about 100 KM south of the balck see coast . My current Grid Locator is KN90rl , in Turkey .
Please send all QSL Cards only Directly to my QSL Mgr for YI1RZ and for SP9/YI1RZ : IK2DUW , no Buerau
Please Follow me on HamSphere as TA / YI1RZ
Also you can follow me on Echolink as YI1RZ
My name is Razi , i was born in Baghdad in 1974 , i have grew up in a family that believes and respects science where my father was a doctor and he finished his studies in medicine in Germany and my mother was a teacher of English language in junior high school .
My story with the Radio started in 1984 , at that time and during the war between Iraq and Iran my father every night was trying to receive the signals of London Broadcasting or Voice of America on very good Radio from Japan model : SANYO Radio & Cassette IC-8800 RP-8800 .
After this incident , I started looking for these signals and stations when my father in work time , i have discovered that the sensitivity of the device to the reception changed when touch the antenna of this device with my hand so i added a piece of wire to the original antenna of the device to increase the length of the antenna , i have found that the sensetivity of the reception increased and the Radio can now get more signals and stations , that was the 2nd incentive to me made me more interested with the Radio and the antenna .
I did dozens of experiments on this topic and my father was helping me to get more information about this object , Unfortunately at that time in my country there was no real interest in these subjects and there was no encouragement for such interests or hobbies, especially for young children.
Passed a long period of time that I was able to become a licensed amateur radio , i got my first License in 2005 and my call sign was YI1RAZ class B , in 2009 i became class A YI1RZ .
I started my activity in HF 20 and 40m Band with Just 10 Watts at that time ( QRP Radio TS-130V ) with Multiband Antenna from Fritzil GPA-50 .
My QTH is Baghdad and my home Locator is : LM23EF , i did most my QSO's from this location .
The below pictures of some equipments that I have in my shack .
1- Homemade 4 - ele Yagi for 6m Band
2- Homemade 2- ele beam for 20m Band
3 - Half Delta Loop Antenna
4- Two Half Delta loop Antenna
5 - Inverted M Antenns for 40m Band
6 - Half Vertical Loop Antenna
7 - Two Half Vertical Loop Antenna
8- Dual Band Vertical Antenna for 40 & 80m Band
9 - Multi Band Vertical Antenna from Fritzil GPA - 50
10 - Triangle Antenna
11- Folded Two Half Vertical Loop Antenna
12- L/4 Vertical Antenna with ground plane for 17m Band
And Below some photos frim Dx Watch website for my HF Activity in many bands and many modes.
I'm also interested in one of the branches of ِAstronomy , it is called Radio Astronomy , This science studying the properties of celestial bodies rather than through the visible light spectrum, but through the radio spectrum , the radio spectrum give us more information about the physical Behavior of these bodies , and to study this science you need special equipments .
My Interest in this science began at the end of 1999 , during one day in this year when i was trying to find some books about the Radio science in one of the public libraries in Baghdad i found a very useful and very interesting book in Arabic language it is : THE RADIO UNIVERSE , By: J.S.Hey , this book show you how do you look up to the sky, but through the radio spectrum and not through the light spectrum . I very much enjoyed the valuable information contained in this book and began to try to apply the some of the experiences in this book .
The closest celestial bodies to our planet , which is considered one of the most radiant orbs of the radio spectrum are the Sun and Jupiter , this book tell you , you can receive these signals ( Radio spectrum ) for Sun and Jupiter on HF bands specially on 18.7 MHz for Jupiter and 20.1 MHz for the Sun .
First , i tried to receive these signals on AM Radio o, SW bands by using good type 4 Bands AM , FM Radio and i did small modification on its antenna , i have added external wire about 10m to the roof of my house , at the beginning i failed to receive the Decametric emissions from the Jupiter because it is weak and i do not know exactly the positions of the Jupiter at that time .
Then , i tried to receive the Radio Bursts from the Sun on 20.1 MHz , and after several attempts , i got it , i could receive the spike signals burst from the Sun as mentioned in the RADIO UNIVERSE book , It was a great moment for me at that time but Unfortunately I did not know how do i record these emissions and how i measure or what units are measured.
In 2005 when i became Ham radio and got my transceivers , i started look again at this field ( RADIO ASTRONOMY ) but with look deeper specially when i found more details about this object in NASA website : http://radiojove.gsfc.nasa.gov/ . i have found more detials about the Decametric emission and solar bursts also about how you can build your own radio astronomy telescope by simple dipole antenna . i started using RACAL Receiver ( 100 KHz to 30 MHz ) with simple in phase two dipole array @ 20.1 MHz .
I have spent long time when i could receive first radio bursts from the Sun also i could record it as mp3 file also uploaded to my youtube account . below you will see my first antenna for radio astronomy it is called : 2- ele Horizontal Dipole in Phase Array , this array is suitable to receive the Decametric emission from the Jupiter and the Solar Bursts from the Sun .
And Below you can hear some solar Bursts received by this antenna and the RACAL Receiver .
In 2011 i have got a very good receiver has multi functions , it is : JRC NRD-545 DSP Receiver from 100KHZ to 2 GHz all moeds with variable bandwidth , i could receive many signals from the Sun with this receiver.
Also i did small modification to the Digital Sattelite receiver and associated it with the JRC receiver to receive the Galactic Background Radioation on 11 cm near 2.7 GHz , it is simple project but it was very nice . below the photos about this project :

My other Hobby
Best regards for all ham radio around the world.
See you on the air... de Razi / YI1RZ
